Figure 9 is a view similar'to Figure 7 but with the lock ypartsdisclosed ina different The present embodiment of the invention isincorporated in a lock 11 disposed in a suitable cavity 12 provided inthe free edge portion 13 of a door 14, and which isarvranged to beoperated from the inner and out-er sides of the doorby means of knobs 15and 16. kThe boltsy 17 of the lock isarranged to normally extend fromtheouter endof a Vbolt casing 18 mounted in the. door edge '18, such casing,being laterally Vflanged adjacent the point of emergence of the bolttherefrom whereby it may be mounted in fixed relation in and to the dooredge,A it being noted' that the casing flange is also arranged toconceal the mouth of the portion of the cavity y12 which extends-to thedoor edge.

Slidably mounted in the casing 18 isa bolt yoke or latch plate member19v for actuating ythe bolt 17, such member being here shown hollow andof generallyrectangularoutline and being urged to assume and maintain anouter position by reason of a spring21 operatively engaged behind it.The forward end ofthe latch plate 19 is perforated as at 22 'for theslidingreception olfa shank 23 ex'- tending inwardly from the bolt, such-shank beingsp'rovided at its inner extremity with.

an enlarged head 24 which is arranged to limit the outward movement ofthe bolt shank through the opening 22. A compression spring 26-isdisposed about the shank 23 and between the inner end of the bolt headand the outer end of the latch plate 19 whereby the'bolt is arranged tobe normally held extended from the latch plate for retraction therewith,'and at the same time may be retracted independently of the latch plate.Journalled in the casing 18 to extend horizontally therethrough is alatch actuator 27 having extending therefrom intermediate the casingwalls an arm 28 arranged for engagerment with the latch plate 19in suchAmanner that a rotation of the actuator fromthe nor-Y mal position shownin Figure-will effecta retractive displacementof the'latch plate.Preferably, and as shown, the actuator arm 28 is arranged for engagementwith the latch plate bothat the upper and lower sides thereof whereby arotation of the actuator in either possible direction may lretract thelatch plate. s y Y The. casing 18, itis noted, is formed with Ygenerally like and transversely separable sec tions V29 and 3,1, theplane of separation of thevsections extending longitudinally ofthecasing and perpendicular to the vaxis of rotation of the actuator 27Ends 32 and 33 of the casing sections are extended for an overlappingrelation, and flat flanges 37 and 38 at the other ends of the respectivesections are:y arranged to lie in coplanar relation whereby they may besimultaneously en- 'f--gaged in opposedgrooves 39 provided at theybackijof an edge plate 41.` The plate 41 is perforated to permittheprotrusion of the bolt therethrough, it being noted that 'the `boltmust be pushed back `beyond the plane ofthe plate 41 duringtheinstallation orremoval .off the plate. The plate`41 is also per- Vthespindle slidably engages the perforation esv 43.` As shown,-. theperforation and spindle are of like polygonal section for effecting anoperative engagement thereof. The ends of the spindle 44 extend fromboth sidesof the actuator, and arel arranged tobe connected to the knobsland 16 whereby they may be ,operatedwthereby rIvhe spindle 44 isarranged to carrv'the knobl infixed relation thereto vat all times.VAs'shown,'the spindle end portion 46arranged for engagement with theknob 15 is threaded andV has-threadedly and adjustably engaged thereon amember 47 providing a conically tapered friction face 48 for engagementin a-complementary vhead bearing against the knob at the outer end ofits perforation 53. In this manner, .with the member 47, set asrequired, the screw 52J may be tightened against the knob to 1 clampAthe knob Vbetween its head and the member 47. l Y t The knob 16, it willbenoted, vcarries a key controlled tumbler barrelg54 axially jouinalledV therein, theinner end of the barrel being provided with a recessinto which theY inner key end protrudes when the key is fully engaged inthe barrel, the latter relation being indicated in Figure 4. The sleeveportion 56 ofthe knob 16 is removably secured'to the knob portion properwhich carries the tumbler barrel, by means of screws 57 engagedvthrougha radial flan-ge at the outer end of the sleeve, said fiange and theopposed knob surface preferably being provided with interlockingportions for preventing a relative' rotation of the sleeve and knobindependently of the screws 57.

Means are provided whereby the knob 16 and spindle-44 may be lockedtogether against relative rotation or released from such lockedengagement by ,appropriate manipulations Kof the inner knob 15. Asshown, the bore of the sleeve 56 is formed with three distinct portions58, 59eand 61 of differing diameters. The .bore-portion 58 is ofcircular section and has thesmallest diameter ofy the three boreportions,.the diameter thereof being, however, 'larger than the; spindleportion engaged therethrough. Slidably mounted on. the spindle is aspool-shaped member 62 having one end iange 63 disposed inwardly of theinnerend ofthe sleeve yand the other end .flange 64 engaging in theintermediate bore portion 59. A compression spring 65 is mounted on themember 62 in encircling relation thereto, with one end of the springengaging the iiange 64 while the other end engages a shoulder 66 on theinner end of the sleeve56. While slidable on the spindle, the member 62is arranged for rotation therewith, .such being here shown effected byforming the bore of the member and the spindle portion engaged therebyof polygonal section. In this manner, the member 62 is arranged forrotation with the spindle at all times.

Extending from the inner end of the sleeve face 56 ,is a taperedprojection 68, said projection being arranged for engagement in aVspindle permits an adjustable mounting the knob axially along thespindle,

radial notch 69 provided' in the opposed flange 63 of the member`62..The engage- -ment of the proj ection 68 in the notch 69, it

will be noted, locks the sleeve 56 to the member 62 for rotationtherewith and with the spindle, it being further noted that the spring65 is constant-ly operative to urge such engagement between the sleeveand member. Threadedly engaging the spindle outwardly of and againstthe'inember 62 is a nut 71, said nut being longitudinally slidablek andnonrotatably engaged in the sleeve bore portion 59. Preferably, and asshown, the nut 71 is hexagonal and the bore .portion'engageable therebyis of like section whereby rotation of the nut in andv with respect tothe sleeve is prevented. It' will now be clear that if the spindle beaxially displaced to release the projection 68 from the notch 69 againstthe resistance of the spring 65, a relative rotation of the knob 16 andspindle 44 is permitted. And it will be further noted that the threadedengagement of the nut 71 with th;

Mounted on the spindle 44 outwardly of the nut 71 and in the outer boreportion 61 is a sleeve 72. The sleeve 72 slidably and non-rotatablyengages thespindle, the spindle and sleeve bore being of polygonal`section for this purpose, it now being noted that the entire spindleportion engageable within the knob sleeve is conveniently of the samesection, since the member A62 is similarly engaged with the spindle Vatthe inner end of said sleeve. The outer end of the sleeve 72 extendsinto the tubular barrel recess 55 and is diametrically slotted toreceive the tip of a proper key 7 3. With the'knob 16 relatively fixed,the insertion of the keyreleases the tumbler barrel for rotation in theknob and the spindle is turnable directly by the key, providing, ofcourse, that the knob sleeve is not locked to the spindleby the member62, which condition obtains when the spindle is disposed to free theprojection 68 from the notch 69. In this manner, the spindle is arrangedfor a direct key operation thereof when the knob is inoperativewithrespect thereto. It is noted that the sleeve 72 is freel.v1 rotatable inthe bore portion 61 and is held against axial displacement therein byreason of its engagement between the tumblerbarrel and the shoulder 74defining the inner end of said bore portion. s n

Means are provided for holding the outer knob 16 in lixed relation tothe door andthe belt casing 18, said means being hereinafter described.With the knob and its sleeve 56 thus held against movement, the spindler44 pull on the inner door knob 15. Since such `same time permits the useof a key for opening the door from the outside thereof wherebythe lockthen constitutes a key lock, means are provided whereby the spindle maybe held set in said position against the resistance of the spring 65.Accordingly, and as shown, a plate 75 is mounted on the spindle 44between the bolt casing 18 and the outer knob sleeve 56, said platebeingswivelled on the spindle for axial displacement therewith. In thepresent embodiment, the plate 75 is provided witha radial notch 76extending from its center and having the plate edge portions at itsinner end engageable in'an annular groove 77 provided in thel spindle.vExtending axially from opposite sides of the plate 75 toward the lfnobsleeve 56 are extensions 78, said extensions being arranged for slidingengagement in a pair of cooperating slots 79 providedin the cylindricalsurface of the sleeve. `When the plate extensions 78 are engagedjin theslots 79, the plate 75 lis arranged 'to vbe held against lateral removalfrom its swivelled engagementv with the spindie. it being also notedthat such engagement of the extensions in the slots locks the platelagainst relative rotation with respectl to the sleeve. The extensions 78are of such length that they maintain their engagement in the slotskboth when the spindle is moved inwardly to effect a release of lthe'knob 16 therefrom and for different adjusted distances between Y theknob sleeve andthe bolt casing.

Extending laterally from latch plate 19 through slots 81 provided in thebolt casing 18 and toward the plate 75 is an extension 82, saidextension being provided with an opening 83 adjacent its outer extremityfor the reception of a radial extension or detent 84 provided on theplate 75. The free edge of the latch plate extension 82 is bevelled andthis extension is so related to the plate extension 84 that when thelatter is moved inwardly, it forces back the former against the resist'-ance of the latch plate' spring 21 until the detent 84 enters theopening 83. In this mannen a simple detent means is provided forholdingr the spindle in its inner position. It is noted that when thedetent 82 is engaged in the opening 83. a rotation of the plate 75, andso of the knob 16,- is prevented, thereby both holding the knob fixedduring the actuation of the key therein and indicating that the door islocked. Preferabl i and as showny n u a 7 pairs of oppositely relatedextensions 82 and `84 are provided on the latch plate 19 and platerespectively whereby the positions of the knobs may be reversed withrespect to the bolt casing. It is noted that the relation ofthe partswhen the spindle is' set iny its inner position is shown inVFigure 9,while Figures11,x4, 5 vand '7 disclose thelock parts .as related .whenthe outer Vknob 16 is operable for actuating the spindle. Y

Release of the spindle to return to its outer position is .effectedWhenever the spindleti's rotated to displace the latch plate fordisengaging the extension opening SSfrom the detent 84. In this manner,a rotation ofthe spindle from either side-of the-door restores thespindle `to its outerposition and renders the lock operable bymeans ofkthe outside knob, it being clear that the'lock is always operable'bymeans ofthe inner knob. This feature as to the ldisposal of the spindleis particularly valuable when the lock is used on inside doors, sincethelock mustl be deliberately set for key Voperation following each openingactuation thereof.

' An escutcheon plate 85 for engagement against the outer door surfaceis mounted on the sleeve 5G of the outer knob 16. As shown, the plate 85is of circular outline and is provided with a circular opening 86 forthe reception of the sleeve v56; vThe sleeve 5G, it is noted, isprovided with an annular groove 8T adjacent its inner end, said grooveextending substantially to the bottom of` the slots 79.

.Projections 8S entend inwardly from the edge of the escutcheon opening86 for engagement in the groove 87, said projections being placed Vinsaid groove by advancing them `through the slots 7 9 as far as thegroove and then rotating the escntcheon plate to agreater or less degreeabout the sleeve. The escutcheon plate, it is noted, extends outwardlyalong the sleeve and cooperates with the knob to hold an annular shell89 in place, said shell completing the concealment of the sleeve.

.Extending axially inward-ly from the escutcheon plate 85, is acylindrical shell 91, said shell being cutaway at opposite sides toreceive the bolt casing 18 transversely therethrough, preferably inlitt-ed relation. Seg mental webs92 are provided across the inner endsof the portions of the shell 91, said .webs beingprovided with threadedperforations 93.- AA plate 94 is provided for disposal against the innerdoor side, said plate being perforated for Vthe' freel reception of thespindle 44 therethrough. Screws 95 extend through the plate 94 forengagementrin the perforations 93 of the webs 92 whereby the door isarranged to be clamped between said vplateand the escutcheon plate 85.The nut 47, it is noted, is preferably arranged to be disposed closelyadjacent the plate 94 when the spindle is in itsv outer position, andashere shown said nut is provided with an exftension for fitted engagementinthe plate perforation at the spindle whereby the plate may be properlyset before the screws 95 are tightened.

It will now be clear that with the lock of Vmy invention installed on adoor and having 'the knob spindle `inits outer position, a per--son'mayactuate the lock for opening the door by means of either knob.If,`however, the

person wishes to prevent the opening of the door from the outside, itismerely necessary ing 83 of the llatch'plate extension 82. The

use of a vrkey in the tumbler barrcl54 is then required for opening thedoor froin'the outside. By vand upon the useof a key, or the opening'ofthedoorv by means of the inner knob, the spindle and inner knob arefreed to assume their outer position whereby the outer knobisautomatically restored to its operativeness.` The adjustable mountingof the knobs onthe. spindle and the Vreversibility of the operativeparts` for alternately connecting the .outer knob with the latch plateand spindleV makesv possible the use of a single model of the lock ondoors of different thickness and doors hung in various relations totheir openings, whereby the lock is arranged for universal applicationwithout alteration.
